Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=false, destructiveHint=false and idempotentHint=true, so the mutation and safety profile is covered structurally. The description adds only the 'or feed' broadening and otherwise restates the title, saying nothing about required site verification or what failure looks like. With annotations carrying the weight, this is acceptable but thin.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence with no wasted words. It is efficient, though its brevity borders on under-specification rather than disciplined concision.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a two-parameter mutation tool with full schema coverage, complete annotations and no output schema, the essentials are covered by structured fields. What remains missing is workflow context — the siteUrl-must-match-listing prerequisite and verification requirements — which the description leaves entirely to the schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the schema itself is richer than the description, including the critical instruction that siteUrl must match exactly what bing_list_sites returns. The description contributes no parameter meaning whatsoever, so it adds nothing over the structured field documentation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description gives a specific verb and resource (submit a sitemap/feed to Bing Webmaster Tools) and naming 'Bing' implicitly separates it from gsc_submit_sitemap and yandex_submit_sitemap siblings. It also broadens the scope slightly beyond the title by including feeds. It stops short of explicitly contrasting with bing_submit_urls, which pushes URLs rather than sitemaps.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no when-to-use guidance at all: nothing says whether the site must already be verified in Bing, whether the sitemap must be reachable, or when to choose bing_submit_urls or bing_list_sitemaps instead. The agent must infer the workflow from sibling names alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
